Title: Brake controller of vehicle
Inventor: INAGAKI HIROMI
IPC: B60T8/1755
Filed: 1995-07-14
Abstract: PROBLEM TO BE SOLVED: To improve braking performance by changing a brake control amount according to a case where a required counter moment is relatively small after the directions of the target yaw rate and an actual yaw rate are reversed, and a case where a required counter moment is large after both directions of yaw rates are made to be equal to each other. SOLUTION: A vehicle body speed VV is estimated 5 from the wheel speed in traveling of a vehicle, and the target yaw rate YB is determined 7 from this vehicle body speed VV and the steering angle θ. Yaw control is performed by controlling right and left driving wheel brakes by a yaw control means 9 on the basis of the deviation between an actual yaw rate YA and the target yaw rate YB obtained by a yaw rate detecting means 8. This Yaw control means 9 changes a brake operation control amount according to the magnitude of the required counter moment by determining the brake operating control amount in a case where the directions of the target yaw rate YB and the actual yaw rate YA, are opposite to each other smaller than that in a case where the directions of the target yaw rate YB and the actual yaw rate YA are equal to each other.

While the stage 20 is moved in the vicinity of this stored position, the wavefront aberration is calculated on each occasion and a distance of transfer of the lens 8 whereat the wavefront aberration becomes the minimum value is stored. Next, the lens 8 to be inspected is transferred manually to a position whereat a vertex reflection occurs, and after the distance of transfer of the lens 8 whereat the wavefront aberration is the minimum is stored, the concave-convex state of the surface of the lens 8 on the interferometer side is determined. Then, calculation of a refractive index is conducted according to a prescribed operational formula.
